Performance Optimization of Nonorthogonal MFSK for Symbol-by-Symbol Coherent Detection [PDF]
SensorsM-ary frequency-shift keying (MFSK) is employed for several applications, including Internet-of-Things (IoT) and sensor-based communications. Previous studies have demonstrated that coherent detection of well-designed nonorthogonal MFSK signals ...

Dual-Polarization Ambient Backscatter Communications and Signal Detection
Sensors, 2023 Ambient backscatter communication (AmBC), an emerging mechanism for batteryless communications that can utilize ambient radio-frequency signals to modulate information and thus reduce power consumption, has attracted considerable attention and has been ...

Capacity Analysis and Data Detection of OvTDM-MIMO System
IEEE Access, 2023 It is well known that the channel capacity of traditional MIMO systems is positively correlated with the number of antennas, so MIMO systems usually use more antennas to meet higher system capacity requirements, which is increasingly conflicting with the

Analysis of Low Probability of Detection Capability for Chaotic Standard Map-Based FH-OFDMA System
Applied Sciences, 2021 A frequency hopping orthogonal frequency division multiple access (FH-OFDMA) can provide low probability of detection (LPD) and anti-jamming capabilities to users against adversary detectors. To obtain an extreme LPD capability that cannot be provided by

Fast Multi-Symbol Based Iterative Detectors for UWB Communications
EURASIP Journal on Advances in Signal Processing, 2010 Ultra-wideband (UWB) impulse radios have shown great potential in wireless local area networks for localization, coexistence with other services, and low probability of interception and detection. However, low transmission power and high multipath effect
